WHlFFLETREE-HOOK.

SPECIFICATION formingpart of Letters Patent No. 251,769, dated January 3, 1882.

Application filed September 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, TRUMAN W. DE TRAY, of Kenton, in the county of Hardin and State Ohio, have invented new and useful Improve- 5 ments in Single-Tree Hooks, of which the following is a specification.

The object of my invention is to construct the single or double tree hooks or the ferrules for neck-yokcs in such a manner as to avoid to the use of nails, screws, bolts, or like devices for attaching them to the single-tree or other like appliance, and also to permit of their beingtightened should they becomeloose through the shrinkage of the wood; and to that end :5 the invention consists chiefly in forming a series of spurs, commonly called hawks-oill spurs, upon the inner periphery of the sleeves otthe single-tree hooks, and constructing them of wrought iron, preferably, to fit over ashoul- 2o der formed on the single-tree or double-tree.

The invention further consists in providing the outer end of the sleeve with a peripheral flange fitting upon the outer end of the singletrec.

25 In the accompanying drawings, Figure 1 is an isometrical view; and Fig. 2, a longitudinal section on line :0 0c of Fig. 1, illustrating clearly my invention.

'A represents the sleeve of the single-tree 3o hook or the ring-sleeve of a ntckyoke, the

former being provided with the hook (I, the latter with an eye, to Which the ring is attached. At the outer end of the sleeve of the singletree hook is a peripheral inwardly-projecting 5 flange, a, adapted to fit over the outer end of the single or double tree, and upon the inner periphery of said sleeve are formed a series of spurs, 1), adapted to fit over a'shoulder, 0, formed on the single-tree, as shown. When ap- 4o plied to a single-tree thehook-sleeve is slipped or forced over its ends in proper position or shrunk thereon, and the spurs are hammered down over the shoulder 0, thus securing the hook firmly in position withouthaving recourse to the usual method of nailing or screwing said devices to the single-trees. The flange a holds the sleeve against inward motion and the spurs b hold said sleeve against outward motion and against rotation. Should the sleeve become loosened in consequence of the shrinkage of the wood, said sleeve may be readily tightened by tightening or hammering down the spurs b.

Centrally of the double-tree, at that point where the ring-sleeve is applied, said tree or neck-yoke, as the case may be, is provided with two shoulders, c, on opposite sides of the sleeve, which in this case has, instead of a flange, a, at one end, a second series of spurs, which prevent the end motion of said sleeve as well as its rotation upon the tree.

It will be observed that by means of this construction I provide a firm bearing for the sleeves, while by my improved construction and arrangement of said sleeves I provide a simple means of attachment without weakening the bearing for such sleeve by the usual driving of nails or screws, as well as means to tighten the sleeves should they become loosened by reason of shrinkage of the wood.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-- 1. The combination, with the sleeve of a single-tree book, of a series of spurs, b, upon one end and an in wardlyproiecting flange, a, upon the other end, as and for the purpose specificd.

2. In combination with a single or double tree having the shoulders c, the sleeves, A, having the spurs b and flanges a, applied and operating as and for the purpose specifi d.

In witness that I claim the foregoing I have hereunto set my hand this 4th day of December, 1880.
